Count losses

Hi, I would need a chunk of code that I can paste in my EAs for MT4 (no DLL, no scripts).

The code should output a variable VAR that I will use in my conditions for trading.

VAR should be 0 if X or more trades in the last Y trades were losses, else VAR = 1.
If the total number of trades is less than Y, VAR = 1.
X and Y should be input values to be entered when the EA is loaded.

Example. If I input the values 5 for X and 10 for Y,
VAR = 1 if in the last 10 trades the number of losses were 4 or less;
VAR = 0 if in the last 10 trades the number of losses were 5 or more.

Input: values for X and Y
Output: variable VAR that I can place in the conditions for sending the order

Important: this function must me EA-magicnumber specific (not EA specific). In other words, the count of number of trades and number of losses must be about the specific EA-magicnumber the code is pasted into.

Thank you
